Reseed a Lawn (continued)
Fertilize and compost
You want the richest soil possible for
germinating seeds and existing grass. To enrich
your soil:
Fertilize. If you're reseeding the
entire lawn, you don't need to fertilize now,
because it will be gone by the time the grass
germinates and can use it. To nurture existing
grass, use a light fertilizer (you'll be
fertilizing the lawn again in three weeks, when
the new grass can also benefit from it). Spread it
with a broadcast spreader, which will apply
it more evenly over a broader area than a drop
spreader, which simply drops the fertilizer as you
walk along. (Step 4 explains how to use a
spreader.)
Compost. Some experts recommend composting
before reseeding. If you don't compost, you'll
need to break up the soil to plant the seed (see
the following section, "If you didn't compost").
Spreading compost is easy, it enriches your soil,
and it's soft enough that watering alone will
push the seeds down into the soil. You'll need
enough to cover the lawn with a 1/2-inch
(1.25-centimeter) layer. Give the square footage
of your lawn to a compost dealer, which should be
listed in the phone book under topsoil, and he
or she will recommend the right amount. To
calculate square footage, multiply length by
width.
To distribute the compost, load it into a
wheelbarrow and pile it around the lawn in four or
five strategic spots. It's OK to spread compost over established grass. Rake the compost out from
these piles until the whole lawn is lightly
covered. Note: Don't cover the lawn any
deeper than 1/2 inch (1.25 centimeters). Too much
compost can ruin it the same way too much
fertilizer can.
You can help the remaining grass break through
the compost by distributing it further with a
fan rake. This will also help the compost
settle closer to the soil. If you have an
electric leaf blower, it can help blow the
compost down closer to the soil and even it out.
If you didn't compost, break up the
soil. Take a spade and chop the soil 2 inches
(5 centimeters) deep, leaving clods the
size of golf balls or marbles. You may prefer this
method if you already have good soil and you're only reseeding a few brown spots.
